Search for direct top squark pair production in final states with two leptons in √s=13 TeV pp collisions with the ATLAS detector

Popis výsledku v původním jazyce

The results of a search for direct pair production of top squarks in events with two opposite-charge leptons (electrons or muons) are reported, using 36.1 fb−1 of integrated luminosity from proton–proton collisions at √s=13 TeV collected by the ATLAS detector at the Large Hadron Collider. To cover a range of mass differences between the top squark t~ and lighter supersymmetric particles, four possible decay modes of the top squark are targeted with dedicated selections: the decay t~→bχ~±1 into a b-quark and the lightest chargino with χ~±1→Wχ~01 , the decay t~→tχ~01 into an on-shell top quark and the lightest neutralino, the three-body decay t~→bWχ~01 and the four-body decay t~→bℓνχ~01 . No significant excess of events is observed above the Standard Model background for any selection, and limits on top squarks are set as a function of the t~ and χ~01 masses.
